HEATING ATTACHMENT FOR GRATES.

Specification of Letters Patent.

Patented July 30, 1907.

Application filed November 12,1906. Serial No. 842,988.

To all whom it may concern:

Be it known that 1, FRANK A. DnLrn, a citizen of the United States, and a resident of New Orleans, in the parish of Orleans and State of Louisiana, have invented an Improved Heating Attachment for Grates, of which the following is a specification.

My invention is an improved heating attachment for open grates, the same consisting of one or more return fines or pipes which are detachably connected with a front plate adapted to cover the space above the grate basket and projecting therefrom into the room or apartment where the grate is located. The said plate is hinged to the grate frame so that it may be swung laterally together with the aforesaid return pipes or fiues, when it is desired to replenish the grate basket.

The details of construction, arrangement and operation of my attachment are as hereinafter described, the

same being illustrated in the accompanying drawings in whi ch Figure l is a perspective view of the main parts constituting the attachment. Fig. 2 is a plan view of the pipe or flue-attachment and a horizontal section of the grate frame, and the front plate or cover to which the fines are attached. Fig. 3 is aface view of the grate front or cover. Fig. 4 is in part a side view and in part a vertical section of the attachment, the section including the grate. Fig. 5 is a horizontal section of the attachment. Fig. 6 is a front view of the grate frame the attachment being shown swung open and at one side of the grate frame. Fig. 7 is a side view of a device serving as a support for the outer end of the flue attachment.

A see especially Figs. 4 and 6 indicates a grate frame, and B a grate-basket arranged therein, both of which may be of ordinary construction.

G are two return flues or pipes arranged side by side horizontally and detachably connected with a plate D which serves as a cover for the open space above the grate basket B. The part D is hinged to one side of the grate frame A, see especially Fig. 6, so that it may be swung laterally to open or close the grate space as conditions require. The lower edge of the cover D is formed as an outwardly projecting flange d, which, when the cover is closed as shown in Fig. 4 bears upon the curved front bar of the grate basket 13. A suitable latching device may be employed for locking the plate D and its flue attachment 0 in such closed position. The pipes or flues C are practically U-shaped and project their entire length into the room or apartment where the grate is located. A horizontal baffle plate E is arranged about the middle of the space above the grate basket B, or midway between the upper and lower openings of the pipes or flues C. This plate is supported loosely upon horizontal projections F which are preferably cast integrally with the grate frame A andextend rearwardly or inwardly therefrom, their inner ends see Fig. 4, being bent to form a hook that engages the brick-work. Thus the projections F provide anchorage for the grate frame by which it is held firmly in place in contact with the brick-work and at the same time performs the service of supports for the flue plate, or diaphragm E. The latter is preferably formed of iron or burnt clay or other material capable of with-- standing heat for a long period. It will be understood that the plate is supported on the anchoring devices F Whenever the flue-heating attachment 0 is employed, but is removed therefrom when the heating attachment is not in use.

The inner ends of fines-G are detachably connected with collars or thimbles (1 see Figs. 1 and 4, which project from and are cast integral with the grate front or cover D. It will be noted that the lower sections of the pipes suiround the lower collars while the upper sections enter and are hence surrounded by the upper collars which arrangement prevents leak or escape of gases of combustion at the joints.

As indicated in Fig. 4, when the plate E is in due position the smoke and heated gases from the basket B pass into the lower sections .of pipes or fiues O and traverse the same, escaping from the.upper sections above the plate E, thereby reentering the space above the grate and passing on into the chimney.

Dampers H see Fig. 4, are arranged at the inner ends of the flues C, the same being mounted on a vertical spindle that passes through the collars to which the fines or pipes C are attached. The dampers afford a perfect control for the rate of combustion and the amount of heat which may be discharged into the apartment. It is apparent that the plate E diverts all the heated products of combustion into the flues C and the large surface provided by the latter enables the room or apartment to be heated quickly. with comparatively small fire in the grate, and the heat is generated being disseminated very rapidly and effectively so that the room may be heated without the delay incident to the use of an ordinary grate. At the same time the escap e into the chimney of air from the room which is more or less heated is effectually prevented. Thus great economy in fuel is effected and the draft of cool air which flows toward the ordinary open grate is cut off or reduced to a minimum. The attachment also constitutes a means for preventing access of children to the fire above the grate besides serving as a fender in case of explosion of particles of coal. The entire attachment may be swung laterally as shown in Fig. 6, to uncover the grate basket B when it is required to place kindling material or coal therein. The attachment greatly increases the heating capacity of an ordinary grate so that a grate of medium size will answer for a comparatively large room, and a variety of grates of different sizes, as is now the common practice, is rendered unnecessary.

In order to provide a convenient support for clothing requiring to be warmed or dried, or dishes or cooking utensils which are to be warmed, I surround the pipes C with a sheet of perforated metal G the. same being attached to the flanges d that project from the front plate D of the grate; see Figs. 1, 4 and 6.

I provide a stay or support for the outer ends of the fines or pipes O, the same consisting as shown in Figs. 2 and 6 chiefly of a rod I and claw K. The rod is provided at one end with a hook 'i that engages the grate front 1) and is screwthreaded at the other to adapt it for attachment of a Wing nut 41". The device K has claws or curved arms projecting laterally and adapted to fit upon the outer rounded ends of fines C and being loosely mounted on the rod I; by rotating the nut i the claw may be adjusted as required to take up all slack.

- i What I claim is 1v The combination, with a grate frame and basket of a heating attachment consisting of a grate front or cover which is hinged to one side of the frame, and pipes or flues detachably secured to said front and projecting therefrom, substantially as described.

2. The combination, with a grate frame and basket and a diaphragm arranged horizontally in the space above the basket, of a heating attachment proper comprising a plate or grate front which is hinged to the grate frame, and a return pipe or flue forming an attachment of the said plate and projecting therefrom, substantially as decribed.

3. The combination, with a grate basket and frame of a heating attachment comprising a plate or grate front. pipes constructed in U-shape form and secured to the grate front, their mouths being in different horizontal planes, and a bailie or fine plate arranged in'the space above the grate basket and intervening the mouths of the pipes, substantially as described.

4. The combination, with a fire-place frame of a heating attachment comprising a plate or fire front which is hinged to the frame and thus supported so as to swing laterally,

and a return flue which is connected with said plate and thus adapted to swing with it, as described.

5. The combination, with a grate frame and basket of a heating attachment comprising a front for the space above the basket and return pipes or fines connected with and projecting laterally from said plate, and a battle consisting of a plate arranged horizontally midway between the ends of the fines, and means for anchoring the grate frame to the brick-work, the same consisting of plates projecting inward and engaging the brickwork and arranged to form supports for the bathe plate, as described.

6. The combination, with the grate heating-attachment comprising a grate front and return lines attached to and projecting horizontally therefrom, of an openwork protector applied to the lines and covering the same, as described.

7 The combination with a grate heating attachment comprising a vertical plate adapted to serve as a grate front and provided with a forwardly projecting base flange of pipes C which are connected with the plate and project laterally therefrom, and a protector formed of material having openings, the same being attached at its inner edge to the aforesaid plate and'extending over and around the pipes, substantially as described.

8. The combination with the grate frame, andswinging front hinged thereto, of return fiues projecting from said front and a stay extending between the front and the outer end of the fines, and comprising a threaded rod, a nut, and claws for engaging the flue ends, as described.

9. The combination with grate frame and front therefor of lines connected therewith, and a stay extending between the outer end of the flues and the said front and including means for taking up slack, as shown and described.

10. An improved heating attachment for grates, co1nprising a plate carrying a horizontal partition and heating return fines, or conduits, whose upper and lower ends communicate with the spaces above and below the partition, and a foraminated or open-work cover surrounding the dues, substantially as described.
